    Multispectral drones have surged in popularity as businesses and researchers uncover the vast potential of data collection offered by these cameras, capturing invaluable details that are invisible to the naked eye. These advanced systems capture data across multiple light spectrums, unveiling details of in water and on land that can’t be seen with the naked eye. From accurate mapping and surveying, revealing topographical details and land use, to the enhancement of crop management and environmental monitoring, multispectral drones are a gateway to uncover a world of hidden details. This blog explores the top multispectral systems in 2024, shining a light on their capabilities and the transformative impact they have across various applications.

    Multispectral Bands

    Each band of a multispectral camera is designed for a unique purpose, contributing to a comprehensive analysis:

    • Coastal Blue: Targets water vegetation analysis and weeds identification in shallow aquatic environments.
    • Blue: Best for atmosphere and deep water imaging, it’s key in detecting water stress and significant differences in plant health.
    • Green: Focused on imaging vegetation and deep water structures, it’s used to measure canopy cover and detect weed growth.
    • Red: Suitable for imaging man-made objects, shallow water, soil, and vegetation, it helps in detecting vegetative growth.
    • Near Infrared: Primarily used for imaging vegetation, it’s instrumental in measuring plant health and productivity.
    • Rededge: Enhances the accuracy of crop classification and is used to detect crop stress, indicating changes in chlorophyll content.

     

    Vegetation Indices

    Vegetation indices are vital tools in remote sensing, offering insights into plant health and soil conditions. They are calculated using data from different spectral bands of light captured by multispectral cameras. Here are some key indices:

    Top 5 Multispectral Systems

     

    1. AgEagle MicaSense RedEdge-P

    Multispectral M3M

    The RedEdge-P is a rugged and high-quality multispectral & RGB sensor designed specifically for UAV and vegetation mapping. It features a high-resolution panchromatic band for pan-sharpened output resolutions and 5 narrow spectral bands perfect for calculating multiple vegetation indices and composites. Some popular applications include plant counting, phenotyping, plant health mapping, fertiliser management, disease identification, species differation, advanced crop scouting and high-res 3D point clouds. Compatible with existing equipment, including DJI Matrice 350, WingtraOne Gen II and a wide range of post-processing and flight planning software.

    2. DJI Mavic 3 Multispectral

    mavic 3 multispectral

    The Mavic 3 Multispectral is a small, foldable drone with a 5 band multispectral camera with RGB. It scans and analyses crop growth with total clarity with a 43 minute flight time. Applications include orchard mapping, aerial surveying, agricultural drone operation, crop prescription maps, and more. The Mavic 3M can also be used for environment and natural resource surveys, such as water enrichment monitoring, forest distribution surveys, urban green area surveys, and more. Together with DJI Terra or DJI SmartFarm Platform, reconstruct high-resolution orchard maps, automatically identify the number of trees, distinguish trees from other obstacles or objects, and generate three-dimensional operation routes for agricultural drones, making operations safer and more efficient.

    3. AgEagle MicaSense Altum-PT

    The Altum-PT is an optimised 3-in-1 solution for advanced remote sensing and agricultural research. This payload has a 12MP high-resolution panchromatic sensor, a FLIR Boson 320×256 thermal sensor, and 5 spectral bands at 3.2MP each. Key benefits include, synchronised multispectral and thermal imagers for pixel-aligned outputs across multiple bands to discern issues at the plant level, even in the early growth stages, including early-stage stand counting. The thermal sensor adds an additional layer of visibility to crop conditions as the temperature of plants changes rapidly under stress conditions. Use cases for this sensor include irrigation scheduling, plant disease detection, plant phenotyping, fruit yield estimations, fruit maturity evaluation and bruise detection, water stress prediction, pressure issues and clogs detection in irrigation systems. Compatible with existing equipment, including DJI Matrice 350, WingtraOne Gen II, and a wide range of post-processing and flight planning software.
